are you referring to the method getVal? Lets look at your code again:



can you show me where in those 2 lines of code you call getVal? i'm not seeing it.

at the bottom.. i thought this establishes the values.

ok i switched it out to String choice = input.nextLine(); seems to work so far

i didnt really understadn the part where u made it clear that rock is not an int value

getVal is simply a method that converts your string to an int. methods are absolutely useless if you never use them. if you want to convert strings to an int, you have to call your method. i dont see you calling it anywhere. where do you think you should call it?

Honestly, we just learned about methods and i do not know or understand it too well and my text book doesnt help either sorry :T

If you input a a string "rock", it will try to store it into int "choice" as you have written. That is the error. Your method setValue or whatever at the bottom is never called. the syntax for calling a method is:

methodToBeCalled(value[s])

or what you should have wrote:

int choice = getVal(input.getInt());

OR

String choice = input.getInt();
int numberChoice = getVal(choice);

you really don't even need the function even, since you could just be using comparisons like if( humanChoice.equals("rock") && computerChoice.equals("scissors")return true;
and then you'd just have the math.Random method do if(roll = 0) computerChoice = "Rock"; or something
